display > Reset oil change interval.Displaying distance to next service
You can have the distance to the next service displayed on the MMI
screen ⇒page 23, fig. 15. The remaining distance to the next
service is updated every time the ignition is switched on (starting at
500 km after a service has been performed).
On a new vehicle, the display will always show the following
message for the first 500 km.
SERVICE IN ----- KM --- DAYS
Caution
The system cannot calculate the figures for the service indicator if
the battery is disconnected from the vehicle, so no service reminder
can be displayed during this time. Please remember that keeping to
the correct service intervals is most important for the service life
and residual value of the vehicle (and especially for the life of the
engine). The period between two services must never be longer than the time specified in the Service Schedule, even if you only
cover a low mileage during this time.
Note
•
Do not reset the display between oil changes - otherwise the
display will be incorrect.
•
The information in the service interval display remains intact if
the battery is disconnected.
•
The distance to the next service cannot be called up if the system
has detected a Priority 1 fault (red symbol).
•
If the service was not performed by a qualified workshop, the oil
change interval display can only be set to “fixed service intervals” of
15,000 km. If you wish to continue with the “LongLife” service, you
will need to have the oil change interval display reset by a qualified
workshop.

On-board computerApplies to vehicles: with on-board computerIntroduction
The on-board computer provides you with useful informa-
tion during a journey, including average and current fuel
consumption, average speed, fuel range and driving time.The following items of information are processed by the on-board
computer and can be shown one after the other on the display in the
instrument cluster.Fuel range
The estimated fuel range is displayed in km. It shows how far the
vehicle can be driven with the amount of fuel left in the tank,
assuming the same style of driving. The fuel range is displayed in
increments of 10 km.
The fuel range is calculated on the basis of the fuel consumption
over the last 30 kilometres. The fuel range will increase accordingly
if you drive in a more economical manner.
Average fuel consumption
This mode displays the average fuel consumption since the memory
was last cancelled in litres/100 km. If required, you can use this
display to adjust your driving style to achieve the desired fuel
consumption.
Current fuel consumption
The display shows the current fuel consumption in litres/100 km. If
required, you can use this display to adjust your driving style to
achieve the desired fuel consumption.
The computer calculates the fuel consumption every 30 metres. The
display switches to l/h (litres per hour) when the vehicle is
stationary.
Average speed
This mode shows the average speed driven since the memory was
last cancelled (in km/h).
Driving time
This display shows the period of time which has elapsed since the
memory was last cancelled.
Distance covered
This display shows the distance you have covered since the memory
was last cancelled.

Note•
The displays for fuel consumption (average and current
consumption), fuel range and speed are shown in metric units. You
can change the measurement units on the MMI display.
•
The information in the memory is cancelled if the battery is
disconnected.
Applies to vehicles: with on-board computerMemory
The on-board computer has two automatic journey
memories.Press RESET button ⇒fig. 20 to switch back and forward
between the functions of on-board computers 1 and 2.
The number in the display ⇒fig. 19 indicates which of the two
memories is currently in use. The figure 1 means that the display is
showing the information in the single journey memory (on-board
computer 1). The figure 2 means that the display is showing the
information in the total journey memory (on-board computer 2).
Single journey memory (on-board computer 1)
The single journey memory processes the information on a journey
from the time the ignition is switched on until it is switched off. If the journey is resumed within two hours after the ignition is
switched off, the new figures are automatically included in the
calculation. The memory is automatically deleted when you resume
driving, if the journey is interrupted for more than two hours.
Total journey memory (on-board computer 2)
Unlike the single journey memory, the total journey memory is not
erased automatically. In this way, you can determine the period for
which you wish the on-board computer to supply figures.
Applies to vehicles: with on-board computerControls
The on-board computer is controlled by means of two
switches on the windscreen wiper lever.– Press the top or bottom of the function selector switch
⇒fig. 20. This displays the on-board computer read-
outs one after the other.The on-board computer can only be operated while the ignition is
switched on. When the ignition is switched on, the display shows
the function that was last selected.
As well as the figures from the on-board computer (computer 1 or
2), the display can also show information from the digital speedom-

Driver information system 28Speed warning functionApplies to vehicles: with speed warning functionIntroduction
The speed warning function can help you keep below a
pre-set maximum speed.The speed warning function will warn you if the vehicle exceeds the
pre-set maximum speed. The system gives an audible warning
signal if the set speed is exceeded by about 3 km/h. A warning
symbol will also appear in the display . On some models the symbol
may look slightly different.
The speed warning function has two different warning speeds,
which operate independently and serve slightly different purposes:
Speed limit warning 1
With speed limit warning 1, the maximum speed can be changed
while driving. The speed limit that has been set remains stored until
the ignition is switched off, or until it is changed or cleared.
The speed limit warning symbol
for speed limit warning 1 will
appear in the display if you exceed the pre-set speed. It goes out
again if the speed is reduced below the set speed limit.
The symbol also goes out if the speed is increased to more than
about 40 km/h above the set speed for at least 10 seconds. This
cancels the speed limit that was originally set.
Setting speed limit warning 1 ⇒page 28.
Speed limit warning 2
You are recommended to store this speed limit warning if you
always wish to be reminded of a particular speed limit. This could
be when driving in countries with general speed limits, or if you
need to keep below a particular speed when winter tyres are fitted,
etc.The speed limit warning symbol
for speed warning 2 will appear
in the display if you exceed the pre-set speed. Unlike speed limit
warning 1, the warning symbol only goes out once the road speed
has dropped below the stored value again.
Setting speed limit warning 2 ⇒page 29.
Note
Please bear in mind that, even with the speed warning function, it is
still important to keep a check on the car's speed with the speedom-
eter and to observe the statutory speed limits.Applies to vehicles: with speed warning functionSetting speed limit warning 1
You can use the button to set, alter or cancel speed

Auto-check controlIntroductionThe auto-check control checks important components and vehicle
systems. These background checks are run constantly, as long as
the ignition is switched on.
A message is displayed in the instrument cluster if a fault should
occur or if any maintenance or repairs are urgently required. This is
accompanied by an audible warning signal. Depending on the
priority of the fault, a red or yellow warning symbol lights up in the
display.
The red symbols indicate a serious malfunction, whereas the yellow
ones represent other malfunctions or items requiring attention.
Additional messages to assist the driver may be shown with the red
or yellow symbols.
Automatic gearbox* function test
The auto-check control automatically checks the vehicle systems
when the ignition is switched on. If the selector lever is in position
P or N, the following instruction will appear:
When stationary apply footbrake while selecting gear
When a gear (R, D etc.) is selected, this message disappears and the
auto-check control function is displayed.
The driver message will disappear 30 seconds after switching on
the ignition or earlier, if there are other driver messages or malfunc-
tions.
